PAC系統(tǒng)的關(guān)鍵技術(shù)
的產(chǎn)生受益于近年來在嵌入式系統(tǒng)領(lǐng)域的發(fā)展與進(jìn)步。在硬件方面,有重意義的包括:嵌入式硬件系統(tǒng)設(shè)計(jì),其中具有代表意義的是CPU技術(shù)的發(fā)展;現(xiàn)場總線技術(shù)的發(fā)展;工業(yè)以太網(wǎng)的廣泛應(yīng)用。在軟件方面則包括:嵌入式實(shí)時操作系統(tǒng);軟邏輯編程技術(shù);嵌入式組態(tài)軟件的發(fā)展等。試分別說明如下:
跟隨摩爾定律的發(fā)展,最新的高性能CPU在獲得更高的處理能力的同時,其體積更小、功耗更低,從而在出眾的計(jì)算能力以及工業(yè)用戶最為關(guān)心的穩(wěn)定性和可靠性方面獲得平衡,使制造廠商有可能去選擇通用的標(biāo)準(zhǔn)的嵌入式系統(tǒng)結(jié)構(gòu)進(jìn)行設(shè)計(jì),擺脫傳統(tǒng)PLC因采用專有的硬件結(jié)構(gòu)體系帶來的局限,使系統(tǒng)具備更為豐富的功能前景和開放性。
在現(xiàn)有面世的PAC系統(tǒng)中,被廣泛采用的是低功耗、高性能的SOC (System On Chip) 核心處理器。這里面既有采用CISC架構(gòu)的CPU,如Mobile Pentium系列CPU,也有采用RISC架構(gòu)的CPU,如ARM系列、SHx系列等,當(dāng)然也有使用MIPS CPU的。綜合比較而言,由于RISC CPU在應(yīng)用于工業(yè)控制系統(tǒng)時所具備的綜合優(yōu)勢,采用RISC CPU的系統(tǒng)占據(jù)了目前市場所供應(yīng)的控制系統(tǒng)的多數(shù)。
在CPU技術(shù)發(fā)展的同時,移動存儲技術(shù)方面也有很大的進(jìn)展,從而使最新的系統(tǒng)可以在付出有限成本的同時,獲得大容量的數(shù)據(jù)存儲空間,以適應(yīng)新的自動化應(yīng)用對不斷增長的數(shù)據(jù)量的要求,同時又可以避免因?yàn)槭褂脵C(jī)械式硬盤帶來的系統(tǒng)崩潰的風(fēng)險。
經(jīng)過14年的紛爭,最后IEC的現(xiàn)場總線標(biāo)準(zhǔn)化組織經(jīng)投票,接納了8種現(xiàn)場總線成為IEC61158現(xiàn)場總線標(biāo)準(zhǔn),即:FF H1,Control Net,PROFIBUS,INTERBUS,P-Net,World FIP,Swift Net,F(xiàn)F之高速Ethernet即HSE。
